Power that should be supplied to the plurality of functional units is generated. When the main power switch is manually operated by the operator in a state where the generated power is not supplied to the plurality of functional units, control is performed to supply the generated power to the plurality of functional units. In response to the power-on instruction received in a state where the generated power is not supplied to the plurality of functional units, control is provided to supply the generated power to functional units designated in advance among the plurality of functional units. ## Claims ### Claim 1 An information processing apparatus capable of communicating with a power monitoring apparatus via a network, comprising: a power generation unit configured to generate power that should be supplied to a plurality of functional units which the information processing apparatus has; a main power supply switch configured to be manually operated; a receiving unit configured to receive a power-on instruction from the power monitoring apparatus via the network; a first power control unit configured to, in response to said main power switch being manually operated by an operator of the information processing apparatus in a state where the power generated by said power generation unit is not supplied to the plurality of functional units, provide control to supply the power generated by said power generation unit to the plurality of functional units; and a second power control unit configured to, in response to said receiving unit receiving the power-on instruction from the power monitoring apparatus via the network in a state where the power generated by said power generation unit is not supplied to the plurality of functional units, provide control to supply the power generated by said power generation unit to functional units designated in advance among the plurality of functional units. ### Claim 2 (depends on 1) An information processing apparatus according to claim 1, one of the plurality of functional units comprises a first functional unit to which power is supplied irrespective of whether said main power switch is operated and a third power control unit that supplies power to said second power control unit in response to said receiving unit receiving the power-on instruction from the power monitoring apparatus. ### Claim 3 (depends on 1) An information processing apparatus according to claim 1, the functional units designated in advance are functional units that consume a smaller amount of power as compared to the other functional units. ### Claim 4 (depends on 1) An information processing apparatus according to claim 1, wherein the power monitoring apparatus issues the power-on instruction at a power-on time at which power is supplied to the information processing apparatus, and issues a power-off instruction at a power-off time at which power to the information processing apparatus is turned off, and in response to said receiving unit receiving the power-off instruction from the power monitoring apparatus, said second power control unit turns off the information processing apparatus. ### Claim 5 (depends on 4) An information processing apparatus according to claim 4, further comprising a first setting unit configured to set at least one of the power-on time and the power-off time for the power monitoring apparatus. ### Claim 6 (depends on 1) An information processing apparatus according to claim 1, further comprising a second setting unit configured to set, as an effective functional unit, a functional unit that is to be enabled among the plurality of functional units when the power-on instruction is received, wherein according to the effective functional unit set by said second setting unit, said second power control unit determines the functional units designated in advance to which power is supplied. ### Claim 7 A power control method for remotely controlling power to an information processing apparatus having a plurality of functional units to which power is supplied independently of each other, and a main power switch that is manually operated, and capable of communicating with a power monitoring apparatus via a network, comprising: a power generation step of generating power that should be supplied to the plurality of functional units which the information processing apparatus has; a receiving step of receiving a power-on instruction from the power monitoring apparatus via the network; a first power control step of, in response to the main power switch being manually operated by an operator of the information processing apparatus in a state where the power generated in said power generation step is not supplied to the plurality of functional units, providing control to supply the power generated in said power generation step to the plurality of functional units; and a second power control step of, in response to receipt of the power-on instruction from the power monitoring apparatus via the network in said receiving step in a state where the power generated in said power generation step is not supplied to the plurality of functional units, providing control to supply the power generated in said power generation step to functional units designated in advance among the plurality of functional units. ### Claim 8 A computer-readable non-transitory storage medium storing a power control program that implements a power control method for remotely controlling power to an information processing apparatus having a plurality of functional units to which power is supplied independently of each other, and a main power switch that is manually operated, and capable of communicating with a power monitoring apparatus via a network, the method comprising: a power generation step of generating power that should be supplied to the plurality of functional units which the information processing apparatus has; a receiving step of receiving a power-on instruction from the power monitoring apparatus via the network; a first power control step of, in response to the main power switch being manually operated by an operator of the information processing apparatus in a state where the power generated in the power generation step is not supplied to the plurality of functional units, providing control to supply the power generated in the power generation step to the plurality of functional units; and a second power control step of, in response to receipt of the power-on instruction from the power monitoring apparatus via the network in said receiving step in a state where the power generated in the power generation step is not supplied to the plurality of functional units, providing control to supply the power generated in the power generation step to functional units designated in advance among the plurality of functional units.
